Definitions

  • the invention relates to an arrangement for monitoring the tire pressure in the mounted on a motor vehicle Wheels by measuring, comparing and evaluating the Rotational speeds of the individual wheels, with wheel speed sensors and an electronic evaluation circuit that for the rotational speeds of the individual wheels, correction factors determines which is a deviation of the respective Represent the rotational speed of a reference variable, the values of the individual correction factors in a learning phase determined and saved and in an identification phase Deviations in the values of current correction factors from the values of the saved correction factors taking into account the respective driving situation notes as well as evaluates and if the deviations the values of the current correction factors from the values the stored correction factors taking into account a given amount depending on the driving situation exceeded, tire pressure loss signaled.
  • Such a circuit arrangement is from DE 43 37 443 A1 (P 7575) known.
  • the values determined for the individual correction factors are determined for the individual correction factors. Through correlations between the correction factors for typical Driving situations become one of the respective driving situation dependent bandwidth or tolerance range for the correction factors certainly. Will be in the identification phase Exceeding the tolerance range is determined Tire pressure loss signals.
  • the invention is therefore based on the object the driver from the duty of reliable operation of the Relieve calibration key and a simple as possible, with Little effort to get started Learning phase in the required time intervals or after To find certain events.
  • Fig. 1 illustrates a motor vehicle whose wheels VL, VR, HL, HR each with a wheel speed sensor S1 up to S4.
  • These are active or passive sensors, which are fixed on the vehicle wheel are and who when the bike and with this a toothed disc or an encoder E rotates, an alternating signal deliver that corresponds to the wheel speed.
  • Such Sensors are known in numerous training variants.
  • Motor vehicles with an anti-lock braking system (ABS), with a traction control system (ASR, TSC) or a driving stability control (FSR, ASMS) require such Sensors for generating input variables for the Regulation.
  • the output signals of sensors S1 to S4 become one Tire pressure monitoring circuit 1, the electronic Contains part of the arrangement according to the invention, supplied and processed in this circuit.
  • the circuit 1 can be hardwired circuits and / or program controlled Circuits included; the tire pressure monitoring circuit 1 can also be part of the controller of a motor vehicle control system.
  • the circuit 1 is informed of the steering angle via an input LW; another arrow BLS (B rems l Non- Chalter s) and indicated by dashed lines arrow indicate that the regulator is advantageously continued further receives sensor signals and evaluates to assess the current driving situation.
  • BLS B rems l Non- Chalter s
  • the circuit compares in an identification phase 1 the learned values or correction factors with the current ones Evaluate and control a warning lamp WL if when evaluating the current values of the wheel speed sensors S1 to S4 loss of tire pressure is detected.
  • Fig. 2 shows an example of the attachment of a position switch T1, which is here in a vibration damper 2 of the front wheel VL is housed.
  • a position switch T1 which is here in a vibration damper 2 of the front wheel VL is housed.
  • the switch T1 When rebounding of the front wheel as soon as a symbolically represented one Piston 3 inside the vibration damper 2 its upper
  • the switch T1 becomes mechanical or magnetically actuated so that it rebounds this Wheel of the evaluation circuit 1 signals.
  • the signal one of the limit switches or position switches T1 to T4 is sufficient to complete the learning phase of the evaluation circuit 1 to start the arrangement according to the invention again and thereby calibrating the system. A participation of the driver or maintenance personnel is not required.
  • the switches T1 to T4 are inevitably actuated each time the vehicle is lifted using a Lift and every time you change a wheel. An unintentional Rebound of the wheel in an exceptional situation and one associated actuation of one of the switches T1 to T4 is harmless for the function of tire pressure monitoring.
